Anxiety Disorder

Definition

Anxiety Disorder is a complex feeling of apprehension, fear, and worry, often accompanied by pulmonary, cardiac, and other physical sensations. It is a common condition that can be a self-limited physiologic response to a stressor, or it can persist and result in debilitating emotions. When pathologic, it can exist as a primary disorder, or it can be associated with a medical illness or other primary psychiatric illnesses (for example, depression and psychosis).

Causes/ Risk Factors of Anxiety Disorder

Susceptibility to anxiety disorders appears to be associated with multiple factors (listed below). When susceptible individuals are confronted with situations, stress, or trauma clinically significant syndromes may result. An imbalance of neurotransmitters and peptides in the central nervous system appears to be a factor. Noradrenalin, serotonin, and corticotropin-releasing factor may all be involved. In general, the autonomic nervous system, particularly the sympathetic nervous system, regulates many of the symptoms.
